[0002] Nasal oxygen device is used to assist breathing of patients with some respiratory diseases or weak cardiopulmonary function. It can also be used in some special fields, such as plateau operations and oxygen inhalation for athletes.

[0003] Current nasal oxygen devices are generally mounted on the head, with the upper part mounted behind the ear and the lower part clamped on the neck. The nasal oxygen tube is inserted and clamped in the nostril to make the nasal oxygen tube relatively fixed, providing oxygen-assisted breathing for the user.

[0004] However, this fixing method still has some shortcomings. On the one hand, since it is directly inserted and stuck in the nostrils, the user experience is not good, and it is easy to scratch the nasal mucosa when worn for a long time; on the other hand, the nasal oxygen tube is easy to fall off when the user moves violently, and the process of re-wearing is cumbersome. Utility Model Content

The specific technical solution is as follows:

[0006] A non-insertion type nasal oxygen device comprises a nasal oxygen tube, one end of which is connected to an oxygen generator, and a fixing bracket, wherein a fixing piece is provided on the fixing bracket for fixing the fixing bracket to a human head;

[0007] The nasal oxygen tube is fixedly arranged on a fixing bracket, a gas outlet element is arranged at the bottom of the fixing bracket, and the gas outlet element is connected to the other end of the nasal oxygen tube.

[0008] Furthermore: the fixing piece is an elastic headband.

[0009] Furthermore: the air outlet element includes at least one air inlet and two air outlet pipes, the air inlet is connected to the nasal oxygen tube, and the air outlet pipe is used to spray oxygen into the human nasal cavity.

[0010] Furthermore: the gas outlet element further comprises a horizontal rotating shaft, and the gas outlet element is rotatably arranged on the fixed bracket;

[0011] A cavity is provided in the rotating shaft, and the air inlet and the air outlet pipe are both communicated with the cavity.

[0012] Furthermore: the air outlet pipe is bent toward the side where the human face is located.

[0013] Furthermore: the fixing bracket is provided with a four-way fixing buckle, the four-way fixing buckle includes card slots arranged in four directions of upward, downward, left and right respectively, the four card slots are interconnected, and the nasal oxygen tube can be clamped in the card slots.

[0014] Furthermore: the fixing bracket further comprises a strip-shaped support plate integrally connected to the lower part of the elastic headband, and the air outlet element is installed on a side of the strip-shaped support plate away from the human face;

[0015] The strip-shaped support plate is provided with a groove for accommodating the bridge of the nose on one side close to the face of the person.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting a fixed bracket, the air outlet element is located at the bottom of the fixed bracket and is connected to the nasal oxygen tube. The air outlet element can spray oxygen toward the human nasal cavity, so that there is no need to insert the nasal oxygen tube into the nostrils, the user experience is improved, and the fixed bracket is not easy to loosen and fall off, and the user's activities are not easily restricted.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 As shown, a non-insertion nasal oxygen device includes a nasal oxygen tube 1 and a fixed bracket 2. The projection of the fixed bracket 2 in the horizontal direction is roughly T-shaped, and it includes an upper fixing part 21 and a lower strip support plate 23. The fixing bracket 21 in this embodiment is an elastic headband, which is used to fit on the user's head. Due to its elasticity, it can be adaptively fitted at different heights of the head to adjust the position of the air outlet element 22 below. The strip support plate 23 is basically arranged vertically, located between the two eyes, does not block the line of sight, and is close to the contour of the human face. A groove is provided on the inner side thereof for accommodating the bridge of the nose, and an air outlet element 22 is arranged on the outer bottom thereof. One end of the nasal oxygen tube 1 is connected to the oxygen generator, and the other end is connected to the air outlet element 22.

[0024] At the same time, a four-way fixing buckle 3 is also provided on the fixing bracket 2. The four-way fixing buckle 3 includes card slots 31 respectively arranged in four directions of upward, downward, left and right. The four card slots 31 are interconnected. The nasal oxygen tube 1 can be clamped in the card slots 31, so that it can be adjusted to different directions to connect to the oxygen production equipment, which has less restrictions on users.

[0025] Recombination Figure 2 As shown, the air outlet element 22 includes a rotating shaft 223 and an air outlet pipe 222. Two air outlet pipes 222 are provided, both of which are bent toward the human face and are used to spray oxygen into the nasal cavity. A cavity is provided in the rotating shaft 223, and an air inlet 221 is provided thereon. The air inlet 221 is used to connect with the nasal oxygen tube 1, so that the nasal oxygen tube 1 is connected with the air outlet pipe 222, and oxygen is smoothly sprayed into the user's nasal cavity.

[0026] The air outlet element 22 is rotatably disposed on the strip support plate 23 via a rotating shaft 223 . The rotating shaft 223 is disposed horizontally. The angle of the air outlet pipe 222 can be adjusted by rotating the rotating shaft 223 to adapt to different users.

[0027] The utility model arranges the air outlet tube 222 outside the nasal cavity, and the nasal oxygen tube no longer needs to be inserted into the nostrils, which gives the user a better experience. In addition, since the fixed bracket 2 is sleeved on the head, it is not easy to fall off, and the patient's activities are less restricted. The angle of the air outlet tube 222 can be easily adjusted through the rotating shaft 223, which is more convenient to use and suitable for popularization.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
